Sh2-129 HOO Giant Squid and Flying Bat Nebula (First Attempt and Noisier than my 3 Kids) RASA8

Wanted to take a quick crack at the incredibly faint O3 region of the squid nebula in the large Ha cloud of Sh2-129. I was trialing bin 1x1 and 2x2 data with the RASA which is already slightly under sampled with my ASI 1600.

In the end, I combined my 1x1 Ha data with 3 min 2x2 binned O3 data. The data is quite noisy and will need another attempt to really give due justice to this incredible nebula. I used an HOO palette with R = Ha., G =.8 O3 +.2 Ha, B = 03. to give more of an orange color to the hydrogen gas cloud similar to a modified Hubble palette.

The Squid Nebula is a quite faint O3 nebula was discovered in 2011. The nebula is an estimated 2,300 light years from earth and approximately 50 light years across.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
